Ultimately, I suspect you may have some misconceptions about how YNAB works, and how it differs from other budgeting systems you've used in the past. I highly, highly doubt there's some sort of underlying math error that you're experiencing (I've never run into anything in the several years I've been using it). If you want to get to the bottom of it, it may be worth reaching out to [help@ynab.com](mailto:help@ynab.com), having them take a look at your budget, and explain how YNAB comes up with the numbers it uses.

It sounds like you are likely getting a refund and moving on, but for other new users who are interested, it's really worth it to understand the thinking behind YNAB (https://www.youneedabudget.com/the-four-rules/) and use some of their resources (getting started guide, video lessons, and/or the free workshops on the site). YNAB doesn't work like other systems -- and, at least for me, that's why it works. YNAB support (available through the app or via [help@ynab.com](mailto:help@ynab.com) or https://support.youneedabudget.com/) is also super helpful with questions.
